i ATTACHING MEANS FOR FASTENING MEMBERS Application filed June 13, 1907.

T all whom it may concern:

Be it known that I, FRED S; CARR, of Malden, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Attaching Means for Fastening Members, of which the following is a specification.

This invention relates to fastening members which are adapted to be applied to flexible articles, such as'carriage curtains, gloves, etc.

The invention is applicable to fastening members of various kinds, suchas a socket member adapted to enga e a complemental stud member, or an eyel et adapted to engage a cord or lacing. I I

The invention has for its object to provide improved means for clamping a fastening member to a piece of cloth. or other flexible material, in such manner that the said flexible materialwill be firmly enga ed at a number of points, and prevented from being pulled' outwardly from its proper engagement withthe fastening member.

The invention consists in a fastening member having a sheet metal clamping part adapted to bear on one side of the article to which the member is to be attached, and provided with offset portions which are integral with the said clamping part and pro ect therefrom to engage the portion of the article to which the member is applied, the material of each oll'set portion being detached at one edge from the part on which it is formed, to form elongated nonenetrating jaws adapted to engage the artic e by biting or indenting without penetrating it, and arran ed to face inwardly and revent outward isplacement of the portion of the article on which the clalnpin 1 part bears, the member being provided wit a complemental clamping part adapted to hold the article in engagement with the said jaws.

Of the accompanying drawings, forming a part of this specificatiom-Figure 1 represents an edge view of a socket fastening member having a clamping part embodying 1n invention. Fig. 2 represents the inner si es of the parts of the fastening member shown in Fig. 1, said parts being separated. Fig. 3 rep esents an enlarged section on line 3-3 of i 2. Fig. 4 re resents a perspective View of a portion of the clamp art having jaws formed in accordance wit my in-- Vcntion. Fig. 5 represents a section on line Specification of Letters Patent.

55 of Fig. 4, looking toward the left. Fig. 6 represents a sectionalview on an enlarged sc'ale of an eyelet, the setting flange of which is provided with jaws in accordance with my invention.

The same letters of reference indicate the same parts in all the figures.

Referring first to-Figs. 1, 2, 3, and 4, which illustrate a socket fastening member adapted for application to a carriage curtain, a represents the body portion of the socket member, which, as here shown, is composed of an outer plate 5 and an inner plate 6,said plates being rigidly connected in any suitable way to form a casing, in which are located two resilient wire jaws 7 7 adapted to grasp a hooked stud member which is insertible in orifices 8 formed in the front and back plates of the casing. The said socket inernbenis or may be constructed substantially as shown in Letters Patent of the United States No. 803,468, dated October 31, 1.905. The body portion a is provided with flexible inwardlyprojecting prongs 9, which are adapted to penetrate the flexible curtain 10 or other article to which the fastening member is to be applied, said rongs being bent inwardly at their inner emfs against a flat plate or washer 12 placed a ainst the inner side of the curtain to secure the fastening member to the curtain. The plate 12 is provided with slots 13 to receive the pron s 9.

In carrying out t 1e embodiment of my invention shown in Figs-1, 2, 3, and 4, 1 provide a clamping part 14, which is an additional plate of the same form as the plate 12, and is provided with slots 15 to receive the prongs 9. On the plate 14 are formed a series of offset portions 16 by forming a series of slits-or cuts in the material of the late 14 at intervals and forcing the materia at one side of the cuts outwardly from one side of the plate, each offset portion having a thin edge 17 which-constitutes an elongated nonpenetrating jaw 17, at one side of the body of the plate, and are preferably of the arched Each of the form shown in Figs. 4 and 5. jaws 17 stands in a plane substantially at right angles to the side of the plate 14 from which it projects, and the jaws all face inwardly toward theeenter of the plate, as shown in Figs. 2 and 3. The plate 14 is placed upon the prongs 9, and in contact with the inner side of the body a. of the casing, the jaws 17 projecting from the inner side'of the plate, and engaging one side of the sheet 10, y biting or indenting without penetrating the same. The back plateor washer 12 is then placed upon the prongs 9 engaging the opposite side of the sheet 10. After this the prongs are bent inwardly to fpress the plate 12 against the sheet, and to orce the sheet into firm engagement with the jaws 17. The described inwardlyfacing arrangement of the jaws causes them to indent and firmly engagethe sheet, and prevent it from being pu led outwardly in any direction fromthe center of the plate; at the same time the jaws are free from sharp points adapted to penetrate the sheet, so that the latter is clamped or gripped between the plates 14 and 12' without being punctured or penetrated. I Wish to draw a distinction between the elongated curved aws 17 arranged substantially at rightangles with the side of the plate from which they project and facing inwardly toward the center of the plate and adapted to bite or grasp the fabric without penetrating it and conicalbosses or projections and other enetrating prongs which have heretofore men used upon a clamping part to penetrate the sheet to which the clamping part is plied. ,Such penetrating bosses or prongs d not have elongated gripping edges similar to those presented by the non-penetrating-jaws 17 and therefore do not exertthe strong and non-injurious hold upon the fabric that is ex erted by the said jaws. On the other hand, the said penetratin bosses or prongs rupture the fabric and rem or it comparatively easy' for the fabric to tear away when strain exerted outwardly from the center of the clamping part is exerted on the fabric.

In Fig. I show another embodiment of my invention, in which the offset portions 16 the setting'fiange 20 of an eyelet. 21 re rehaving the elongated -j aws 17, are formed on sents the barrel or tube of the eyelet, .whic

the flange 20 and jaws 17 in gripping the material into which the eyelet is inserted. The jaws may be formed with a slight inward inclination toward the center of the member, or in other words, they may i be slightly hooked ,j o give a very'firin hold on the materials W' en the jaws are employed in. conjunction with prongs 9 which penetrate the material, they prevent liability of j the material tearing away from the prongs.

. 1 claim:

A fastening member-having a sheet-metal I clamping part adapl ed to bear on one side of the article towhic the member is to be atv tached, andiprovided with a series of cuts and with oflset ortions, each including one edge of oneof -t e cuts, said edges being raised above the clamping'part, and constituting inwardly facing elongated jaws adapted to engage and prevent outward dis lacement of the portionof the article on wine the clamping part bears, the said member being prw vided witha com lemental clamping part In testimonyw ereofI have affixed my s g nature, in presence of two witnesses.
